This invention relates to machines of the general type disclosed andclaimed in Letters Patent No. 1,289,729, issued December 31, 1918, toHarrison 8. Gripe; The machine shown in said patent isidesignedfor thepurpose of applying paper or'other covering material to the tops andbottoms of boxes whose sidesand" ends have previously been provided'with a covering of similar material. Said inachineicomprises'aworksupport on which the 'box is placed with the portion to becoveredfuppermost, saidwork ilin rear: endofthe machine. 7

support being mounted on a' reciprocating carriage which ismovedinwardly and outwar dly, past the [devices for applying thecovering material, the arrangement being such that when thejcarriageis'in its inner: most position the end ofv a'web of covering material,suitablyooatedwith adhesive, is applied to the outer edgeiof the box,and as the'carriageunoves outward said covering material is drawn fromthe supply and prested down upon the box, the portion appliedto thelatter beingsubsequently sever'ed from the eb.

The present invention has "for its object to provide in a machine ofthis type, proved niecha'nism'for handling the Web of covering materialand forYi-feeding, control} guiding, supporting, holding, and sev- .T heforegoing and other objectsi of the invention, together withmeansiwherebythe same maybe carriednntoefiect will bestbe understoodfromthe following description ofone formorembodiment thereof illustratedin the accompanying; drawings, in which:

Generally speaking saidmachine comprises a main frame 'pro vided Witlrlongitudinal ways inwhich is slidably mounted a carriage'27 carrying a work support 28forsupportingthe boxes to be covered. Said carriage is reciprocated in itsways by mechanism which may be substantiallysimilar to that shown in theGip e patent above referred to, but which as'herein. shown is of thetype disclosed. in 7 October 1,1923, Serial NO.'665,789. V For thepurpose of thejpresent case, this mechanism may be described as followsThe carriage 2-7 is formed at its underside with a lug '30'connectedbylinks 31 with levers 32'sjuitab'ly fulcruined, as at 33, tothe frame 25. Disposed-between the levers 32 is a lever 34 fulcrumed at35 to a bracket' 36 secured: to said frame. The levers32 and 84 areformed with longitudinal slots to receive s'lides l' pivotallyconnected,as at 38,'with each othenand longitudinally adjustable in said slots, bymechanism generally indicated at 89, to 'adjustthe'operative connectionof thelevers 32 and534 and thereby vary-the length of the strok'eofthe-Qcarriage 27, The lever 34 is operate dbyialink4O having acamrroller, 41 which cooperates with a cam ona cani shaft 4-3journalled' in the frame V 25, said linkhaving a forked end embrace ingsaid shaft, whereby said linkgis support ed. The cam shaft/13 isconnectedby'gearing 45 with a main shaft '46] suitablyjournalled'in'the' machine frameand 'ada'pted to receive "power jfroin'any suitable source Supported above th path of movementof the carriage27 .and .the work suppo'rtQS, in

I an auxiliary framefiO:mounted'on the main frame 25,. are the .7devices for' applying the covering material, wliiclris supplied, ashereina'fter more fully described, in the form of V drawitig tlieiwebwitli it, to desjcend upon the. box; and, press P saidgfiveb" down?ripen the eerie; Where i the a'ma e has snared eat adapted, as "thecarriage moves outwardly,

wardly far enough to draw off a suilicient quantity of covering materialto cover the box, said material is severed from the web by a movablecutter Iii-l which is operated by means hereinafter described and whichcooperates with a tired cutter on the auxiliary frame 50.

The mechanism for operating the rollers 52 and 53 may, if desired besubstantially simi lar to the corresponding part in said Gipe patent.its herein shown. however said parts are of the construction andarrangement disclosed and claimed in another application filed Octoberl, .1923 Serial No. 665,788, and for the purpose of the present case maybe described as follows: The applying roller 52 is carried by a pair ofarms of; loosely mounted on a transverse rod 57 sup ported in. theauxiliary frame St]. The arms 56 are connected by links 58 with arms 59on a rock shaft 60 journalled in the frame One of said arms 59 formspart of a hell 0 ank, the other arm (31 of which is provided with a camroller tiflcooperating with a cam 63 on the cam shaft The iiressingroller is carried by a pair of: arms (38 also loosely mounted on the rod57 and connected by links 9 with arms on a rock shaft 71 journalled inthe frame 25 and provided with an arm 72- to which is connected a link7; supported by a link T lt from a rock shaft 75 journalled in saidframe. The link 73 carries a cam roller 76 cooperating with a cam 77 onthe shaft 43.

The web 51 of covering i'naterial is supilied from a roll 80 rotatablysupported in hangers 8t preterably formed integral with and dependingfrom the top of the frame 25 adjacent the rear end of the latter. Saidmaterial is periodically drawn from the roll 80, in order to providesutlicient slack therein for the proper operation of the machine. bymeans of a pull-oil device comprising a roller 8E2 carried by arms 83 ona rock shaft 8- journalled in the frame For the purpose of oscillatingthe rock shaft to swing the arms 83 and roller 82 down 'ardly andforwardly, or to the left in Fig. l. to cause the same to draw thematerial from the roll, the rock shaft Set is provided with an arm 85connected by a link 86 with a crank 87 on the cam shaft The web 51 afterbeing drawn from the roll by the pull-oil roller 89, passes over a guideroller 88 journalled in a suitable support at the rear end of the frameDuring its passage over the roller 88. said web isengaged by atransverse series of spring pressed plungers 89 which are preferablyfitted at: their ends with rubber pads 90 for engaging the paper. Theplungers 89 are ea rrie'd by arms 91 on a transverse rock shaft 92journalle'd in the rear end of the frame 25. The arms 91 areindependently adjust able longitudinally of the rock shaft 92 in orderthat they may be arranged to engage webs of different widths in thedesired manner, said arms being secured in adjusted position on saidrock eha't't by means of set screws 93. The rock shaft 92 is providedwith an arm 94: which is connected by a link 95 with one arm 96 of abell crank fulcrumed at 97 on the frame 25 and the other arm 98 of whichis provided with a cam roller 99 cooperating with a cam 100 on the shaft4-3. The relative arrangement of the cam .100 and crank 87 are such thatwhen the pull-oil roller 82 is actuated to draw the web from the supply,the plungers 89 will be caused to press upon the web with their maximumforce, thereby holdinpsaid web for the pull-oil action of the roller 82,but; when said roller 82 is returi'ied to normal position. duringtheoperation of applying the covering to the box by the mechanismheretofore described, the shaft 952 is rocked to re lieve the pressureof said plungers on the web to a predetermined extent.

From the roller 88 the web 51 passes over a second guide roller 10'] andthence between edge-guides 102 on a rod 10?) supported by uprights 10%from the frame 25, said edgec'uides 102 being longitudinally adjustableon said rod laterally of the machine and be ing secured in adjustedposition thereon by set screws 105. i

From the guides 102 the web passes over guide rollers 10a and MW to themechanism for applying adhesive to one surface thereof. Said mechanismis substantially similar in general. arrangementand function to thatdescribed in the patent to (iipo above referred to and comprises a tank108 for holding the adhesive in liquid form and a roller 10!) journalledin the walls of said tank dipping into the adhesive therein and overwhich the web 51 passes. From the roller said web passes over a guideroller .1 ll) and thence over a transversely arrai'iged scraper lll bywhich the superfluous adhesive is removed therefrom.

Between the guide roller .107 and adhesive applying roller 109, the webpreferably passes between a second pair of edge-guides E2 and thencethrough a device to applying a light tension thereto. Said tension applying device comprises a pair of uprigrhts 3 located respectively atopposite sides of the tank 1.08 and liaving at their upper ends openslots in which are loosely received a pair of rollers 4 and 5 betweenwhich the web passes. The. upper roller 5 is engaged at its ends by leafsprings 11b secured to the tops of uprights whereby said roller ispressed against-t the web and its free rotation yielding 'ly retarded,so as to resist the free movement of the web and apply the desiredtension thereto.

From the adhesive applying; devices the web 51 passes over a suitablenumber of guiding and supporting rollers 11,? and 11S.

The rollers 117 are carried by upright arms 'on'a' longitudinal rod 119upon which the adhesive tank 108 isalsopreferably supported,

' said rodf119 being mounted in uprights 120 on the frame 25, The roller118 is supported by an arm 121 on the rod 57.; V v

The extreme 'en'd of-the "web 51 is supported between successiveapplying opera- Y tions by a series of needles "122 .which correspond ngeneral arran'gement, location andffunction to the needles 'more'fullydescribed in" the patent to Gripe above referred to. Said needles are jlongitudinally reciprocated-to project their ends beneath the end '15 ofthe web to su'pportthe latter and are periodically retracted to releasesaid end whenthe latter is app'lied to the box by the ro'ller'521' Theneedles 122 pass through and are reciprocated in a lubric'ant box 123which ispreferab'ly packed w-ith'waste or similar material'124a"Inaccordancewith the present invention; the 'nee'dles 122 are secured attheirrear ends in arod 125 which isqour- ,nalledatitsendsina pairof arms6 on a 131 connected'by a link 132 with one-arm 133 are bell'crankfulcrumed'on the 'ro'ck-shaft i-springll3l; *T he other arm 135of saidbell crank car-mesa carn' roll'er' 136 'which' coopratesfiwith ac'am 137ori the ca'm shaft 43.
